Generic Binance Security Image

The RANT token, launched on July 3rd without any identifiable team, website, or social media presence, suffered a major exploit just two days later due to flawed smart contract logic. A vulnerability in the _sellBurnliquidityPairTokens function allowed attackers to manipulate token prices by triggering disproportionate burns through small transfers, ultimately distorting liquidity pool reserves. This exploit led to a loss of approximately $203.8K, with the attacker swapping stolen BNB for USDC and bridging it out via the Across Protocol. Security firms like TenArmor and SlowMist flagged the suspicious activity, but the project's anonymous nature and lack of oversight make recovery unlikely, with further details still potentially forthcoming.

About RANT Token

The Reality

The RANT Token smart contract appears to have been launched with flawed smart contract logic.

What Happened

The RANT token on BNB Chain was exploited just two days after launch due to flawed burn logic in its smart contract, allowing an attacker to manipulate prices and steal approximately $204,000.

Technical Details

On July 5, a vulnerability was exploited in the #RANT token on the #BNBChain, resulting in a loss of approximately $204,000. The token had only been live for three days before the incident occurred. The root of the attack lay in the flawed token burn logic, specifically in how the smart contract handled burn operations during token sales. The mechanism allowed attackers to manipulate token prices by exploiting a weakness in how burn amounts were calculated.

The key issue was found in the _sellBurnliquidityPairTokens function, which mistakenly based the burn amount on the user’s transfer amount instead of referencing the liquidity pair’s actual balance. This oversight enabled attackers to perform small token transfers that triggered disproportionate burns from the liquidity pool, distorting the reserve ratios and inflating the token price. This type of manipulation opened the door for the attacker to profit by selling tokens at artificially high prices.

To execute the exploit, the attacker manipulated the price through this flawed logic, stole BNB, then swapped the funds for USDC. Finally, the stolen assets were bridged out using the Across Protocol. The incident highlights the critical need for more secure smart contract logic. Experts recommend adjusting the burn calculation to rely on the liquidity pool’s balance or using a fixed percentage to ensure fairness and prevent such exploits through small-scale manipulations.
